The Reserve Wheel 40|44 provides all-day capability with aerodynamic sensibilities. The 40|44 features a wider, shallower front mixed with a narrower, taller rear wheel, which has proven on the tarmac and in the wind tunnel to deliver speed with the benefit of stability. It’s also designed to provide a comfortable ride all day long. The 40|44 delivers just the note of forgiveness when you need it, to let you keep racking up the miles when others are already legs up on the couch.
